The problem that you are having is with the ^Z that your editor is
setting at the end of your config.lsp file. If it is inconvenient to
arrange that the editor does not put ^Z at the end of the file then a
possible solution is to put the line
(set-syntax-from-char (code-char 26) #\Space)
into the config.lsp. This arranges that ^Z is treated like a space.
I have found another related problem in that if you share lisp files
created and used for CLISP under OS2 (and probably DOS) then the ^M's
that DOS/OS2 editors place in the files causes trouble at the UNIX
sites. I fix this by putting the line
(set-syntax-from-char (code-char 13) #\Space)
in the appropriate source file so that the UNIX machine does not get
confused by the ^M's.
